As expected, Apple is selling the quad-core Mac Pro starting at $2,999 and the six-core model starting at $3,999, while both can be upgraded with eight-core or 12-core processors, with up to 64GB of RAM and with a D700 graphics card for additional fees. The Mac Pro comes with 256GB of onboard flash storage but can be customized with up to 1 terabyte of flash storage.

While Apple initially hoped to ship the Mac Pro by December 30, the company’s online store now lists the device as available to ship in February. Customers who put their orders in early this morning may receive their new computers before the end of the year, but it looks like most people won’t see the new Mac Pro delivered until the later date.

As 9to5Mac points out, the Mac Pro is also available from a handful of third-party retailers where you might have better luck finding it. B&H is accepting pre-orders, while MacMall also has a supply. However, with Apple already pushing back the Mac Pro shipping date, third-party retailers are likely to see similar if not worse delays.

Update: Apple may have seriously underestimated demand on this one. One new report claims customers are being told the redesigned computer won’t ship until early March, though the company’s online store still claims the Mac Pro will be available to ship in February.
